This is the line protection version, not a motor-protective or ground-fault variant; it is intended for feeder and distribution circuit protection where the primary concern is cable and busbar protection against overload and short circuit. Breaking capacity is voltage-dependent: 220 kA at 240 V AC, 154 kA at 415 V, 36 kA at 440 V, and 17 kA at 690 V. Above that, derating is linear: 194 A at 55 °C, 188 A at 60 °C, 182 A at 65 °C, and 176 A at 70 °C. In a sealed or poorly ventilated enclosure where internal ambient reaches 60 °C, the breaker must be loaded to no more than 188 A continuous — a 6 % reduction from nameplate. Account for this in the panel thermal budget. Dimensions are 158 mm height, 105 mm width, 70 mm depth. Suitable for indoor switchboard installation only; not for washdown or outdoor environments without an additional enclosure. ## Auxiliary contacts and release configuration Factory-fitted with 2 auxiliary switches (HQ type — high-rupturing-capacity auxiliary contacts suitable for direct switching of PLC inputs without intermediate relays) and an undervoltage release (UVR). No communication function, no phase failure detection, no voltage trigger, and no ground fault monitoring are built into this variant. If remote monitoring or ground-fault protection is required, it must be added externally via a shunt trip or a separate GFCI module.","metaTitle":"Siemens 3VA1220-6EF32-0DC0 SENTRON MCCB, 200 A, 220 kA at 24","metaDescription":"Siemens SENTRON 3VA1220-6EF32-0DC0 molded case circuit breaker, 200 A rated, TM240 release, 220 kA at 240 V.
